-### BREAKING CHANGES
-
-* the Socket#use() method is removed (see [5c73733](https://github.com/socketio/socket.io/commit/5c737339858d59eab4b5ee2dd6feff0e82c4fe5a))
-
-* Socket#join() and Socket#leave() do not accept a callback argument anymore.
-
-Before:
-
-```js
-socket.join("room1", () => {
- io.to("room1").emit("hello");
-});
-```
-
-After:
-
-```js
-socket.join("room1");
-io.to("room1").emit("hello");
-// or await socket.join("room1"); for custom adapters
-```
-
-* the "connected" map is renamed to "sockets"
-* the Socket#binary() method is removed, as this use case is now covered by the ability to provide your own parser.
-* the 'origins' option is removed
-
-Before:
-
-```js
-new Server(3000, {
-  origins: ["https://example.com"]
-});
-```
-
-The 'origins' option was used in the allowRequest method, in order to
-determine whether the request should pass or not. And the Engine.IO
-server would implicitly add the necessary Access-Control-Allow-xxx
-headers.
-
-After:
-
-```js
-new Server(3000, {
-  cors: {
-    origin: "https://example.com",
-    methods: ["GET", "POST"],
-    allowedHeaders: ["content-type"]
-  }
-});
-```
-
-The already existing 'allowRequest' option can be used for validation:
-
-```js

-
-
-### BREAKING CHANGES
-
-* the 'origins' option is removed
-
-Before:
-
-```js
-new Server(3000, {
-  origins: ["https://example.com"]
-});
-```
-
-The 'origins' option was used in the allowRequest method, in order to
-determine whether the request should pass or not. And the Engine.IO
-server would implicitly add the necessary Access-Control-Allow-xxx
-headers.
-
-After:
-
-```js
-new Server(3000, {
-  cors: {
-    origin: "https://example.com",
-    methods: ["GET", "POST"],
-    allowedHeaders: ["content-type"]
-  }
-});
-```
-
-The already existing 'allowRequest' option can be used for validation:
-
-```js
-new Server(3000, {
-  allowRequest: (req, callback) => {
-    callback(null, req.headers.referer.startsWith("https://example.com"));
-  }
-});
-```
-
-* Socket#rooms is now a Set instead of an object
-
-* Namespace#connected is now a Map instead of an object
-
-* there is no more implicit connection to the default namespace:
-
-```js
-// client-side
-const socket = io("/admin");
-
-// server-side
-io.on("connect", socket => {
-  // not triggered anymore
-})
-
-io.use((socket, next) => {
-  // not triggered anymore
-});
-
-io.of("/admin").use((socket, next) => {
-  // triggered
-});
-```
-
-* the Server#set() method was removed
-
-This method was kept for backward-compatibility with pre-1.0 versions.

-## Features
-
-Socket.IO enables real-time bidirectional event-based communication. It consists of:
-
- a Node.js server (this repository)
- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
-
-Some implementations in other languages are also available:
-
- [Java](https://github.com/socketio/socket.io-client-java)
- [C++](https://github.com/socketio/socket.io-client-cpp)
- [Swift](https://github.com/socketio/socket.io-client-swift)
- [Dart](https://github.com/rikulo/socket.io-client-dart)
- [Python](https://github.com/miguelgrinberg/python-socketio)
- [.NET](https://github.com/doghappy/socket.io-client-csharp)
-
-Its main features are:
-
-#### Reliability
-
-Connections are established even in the presence of:
-  - proxies and load balancers.
-  - personal firewall and antivirus software.
-
-For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
-
-#### Auto-reconnection support
-
-Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://socket.io/docs/v3/client-api/#new-Manager-url-options).
-
-#### Disconnection detection
-
-A heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
-
-That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
-
-#### Binary support
-
-Any serializable data structures can be emitted, including:
-
- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
-
-#### Simple and convenient API
-
-Sample code:
-
-```js
-io.on('connection', socket => {
-  socket.emit('request', /* … */); // emit an event to the socket
-  io.emit('broadcast', /* … */); // emit an event to all connected sockets
-  socket.on('reply', () => { /* … */ }); // listen to the event
-});
-```
-
-#### Cross-browser
-
-Browser support is tested in Sauce Labs:
-
-[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket)
-
-#### Multiplexing support
-
-In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
-
-#### Room support
-
-Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
-
-This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
-
-
-**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).

-## Installation
-
-```bash
-// with npm
-npm install socket.io
-
-// with yarn
-yarn add socket.io

-Please see the documentation [here](https://socket.io/docs/).
+  Creates a new `Server`. Works with and without `new`:

-The source code of the website can be found [here](https://github.com/socketio/socket.io-website). Contributions are welcome!
+  ```js
+  var io = require('socket.io')();
+  // or
+  var Server = require('socket.io');
+  var io = new Server();
+  ```
+
+### Server(opts:Object)
+
+  Optionally, the first or second argument (see below) of the `Server`
+  constructor can be an options object.
+
+  The following options are supported:
+
+  - `serveClient` sets the value for Server#serveClient()
+  - `path` sets the value for Server#path()
+
+  The same options passed to socket.io are always passed to
+  the `engine.io` `Server` that gets created. See engine.io
+  [options](https://github.com/socketio/engine.io#methods-1)
+  as reference.
+
+### Server(srv:http#Server, opts:Object)
+
+  Creates a new `Server` and attaches it to the given `srv`. Optionally
+  `opts` can be passed.
+
+### Server(port:Number, opts:Object)
+
+  Binds socket.io to a new `http.Server` that listens on `port`.
+
+### Server#serveClient(v:Boolean):Server
+
+  If `v` is `true` the attached server (see `Server#attach`) will serve
+  the client files. Defaults to `true`.
+
+  This method has no effect after `attach` is called.
+
+  ```js
+  // pass a server and the `serveClient` option
+  var io = require('socket.io')(http, { serveClient: false });
+
+  // or pass no server and then you can call the method
+  var io = require('socket.io')();
+  io.serveClient(false);
+  io.attach(http);
+  ```
+
+  If no arguments are supplied this method returns the current value.
+
+### Server#path(v:String):Server
+
+  Sets the path `v` under which `engine.io` and the static files will be
+  served. Defaults to `/socket.io`.
+
+  If no arguments are supplied this method returns the current value.
+
+### Server#adapter(v:Adapter):Server
+
+  Sets the adapter `v`. Defaults to an instance of the `Adapter` that
+  ships with socket.io which is memory based. See
+  [socket.io-adapter](https://github.com/socketio/socket.io-adapter).
+
+  If no arguments are supplied this method returns the current value.
+
+### Server#origins(v:String):Server
+
+  Sets the allowed origins `v`. Defaults to any origins being allowed.
+
+  If no arguments are supplied this method returns the current value.
+
+### Server#origins(v:Function):Server
+
+  Sets the allowed origins as dynamic function. Function takes two arguments `origin:String` and `callback(error, success)`, where `success` is a boolean value indicating whether origin is allowed or not.
+
+  __Potential drawbacks__:
+  * in some situations, when it is not possible to determine `origin` it may have value of `*`
+  * As this function will be executed for every request, it is advised to make this function work as fast as possible
+  * If `socket.io` is used together with `Express`, the CORS headers will be affected only for `socket.io` requests. For Express can use [cors](https://github.com/expressjs/cors).
+
+
+### Server#sockets:Namespace
+
+  The default (`/`) namespace.
+
+### Server#attach(srv:http#Server, opts:Object):Server
+
+  Attaches the `Server` to an engine.io instance on `srv` with the
+  supplied `opts` (optionally).
+
+### Server#attach(port:Number, opts:Object):Server
+
+  Attaches the `Server` to an engine.io instance that is bound to `port`
+  with the given `opts` (optionally).
+
+### Server#listen
+
+  Synonym of `Server#attach`.
+
+### Server#bind(srv:engine#Server):Server
+
+  Advanced use only. Binds the server to a specific engine.io `Server`
+  (or compatible API) instance.
+
+### Server#onconnection(socket:engine#Socket):Server
+
+  Advanced use only. Creates a new `socket.io` client from the incoming
+  engine.io (or compatible API) `socket`.
+
+### Server#of(nsp:String):Namespace
+
+  Initializes and retrieves the given `Namespace` by its pathname
+  identifier `nsp`.
+
+  If the namespace was already initialized it returns it immediately.
+
+### Server#emit
+
+  Emits an event to all connected clients. The following two are
+  equivalent:
+
+  ```js
+  var io = require('socket.io')();
+  io.sockets.emit('an event sent to all connected clients');
+  io.emit('an event sent to all connected clients');
+  ```
+
+  For other available methods, see `Namespace` below.
+
+### Server#close([fn:Function])
+
+  Closes socket.io server.
+  
+  The optional `fn` is passed to the `server.close([callback])` method of the 
+  core `net` module and is called on error or when all connections are closed. 
+  The callback is expected to implement the common single argument `err` 
+  signature (if any).
+
+  ```js
+  var Server = require('socket.io');
+  var PORT   = 3030;
+  var server = require('http').Server();
+
+  var io = Server(PORT);
+
+  io.close(); // Close current server
+
+  server.listen(PORT); // PORT is free to use
+
+  io = Server(server);
+  ```
+
+### Server#use
+
+  See `Namespace#use` below.
+
+### Namespace
+
+  Represents a pool of sockets connected under a given scope identified
+  by a pathname (eg: `/chat`).
+
+  By default the client always connects to `/`.
+
+#### Events
+
+  - `connection` / `connect`. Fired upon a connection.
+
+    Parameters:
+    - `Socket` the incoming socket.
+
+### Namespace#name:String
+
+  The namespace identifier property.
+
+### Namespace#connected:Object<Socket>
+
+  Hash of `Socket` objects that are connected to this namespace indexed
+  by `id`.
+
+### Namespace#clients(fn:Function)
+
+  Gets a list of client IDs connected to this namespace (across all nodes if applicable).
+
+  An example to get all clients in a namespace:
+
+  ```js
+  var io = require('socket.io')();
+  io.of('/chat').clients(function(error, clients){
+    if (error) throw error;
+    console.log(clients); // => [PZDoMHjiu8PYfRiKAAAF, Anw2LatarvGVVXEIAAAD]
+  });
+  ```
+
+  An example to get all clients in namespace's room:
+
+  ```js
+  var io = require('socket.io')();
+  io.of('/chat').in('general').clients(function(error, clients){
+    if (error) throw error;
+    console.log(clients); // => [Anw2LatarvGVVXEIAAAD]
+  });
+  ```
+
+  As with broadcasting, the default is all clients from the default namespace ('/'):
+
+  ```js
+  var io = require('socket.io')();
+  io.clients(function(error, clients){
+    if (error) throw error;
+    console.log(clients); // => [6em3d4TJP8Et9EMNAAAA, G5p55dHhGgUnLUctAAAB]
+  });
+  ```
+
+### Namespace#use(fn:Function):Namespace
+
+  Registers a middleware, which is a function that gets executed for
+  every incoming `Socket`, and receives as parameters the socket and a
+  function to optionally defer execution to the next registered
+  middleware.
+
+  ```js
+  var io = require('socket.io')();
+  io.use(function(socket, next){
+    if (socket.request.headers.cookie) return next();
+    next(new Error('Authentication error'));
+  });
+  ```
+
+  Errors passed to middleware callbacks are sent as special `error`
+  packets to clients.
+
+### Socket
+
+  A `Socket` is the fundamental class for interacting with browser
+  clients. A `Socket` belongs to a certain `Namespace` (by default `/`)
+  and uses an underlying `Client` to communicate.
+  
+  It should be noted the `Socket` doesn't relate directly to the actual
+  underlying TCP/IP `socket` and it is only the name of the class.
+
+### Socket#use(fn:Function):Socket
+
+  Registers a middleware, which is a function that gets executed for
+  every incoming `Packet` and receives as parameter the packet and a
+  function to optionally defer execution to the next registered
+  middleware.
+
+  ```js
+  var io = require('socket.io')();
+  io.on('connection', function(socket){
+    socket.use(function(packet, next){
+      if (packet.doge === true) return next();
+      next(new Error('Not a doge error'));
+  });
+  ```
+
+  Errors passed to middleware callbacks are sent as special `error`
+  packets to clients.
+
+### Socket#rooms:Object
+
+  A hash of strings identifying the rooms this client is in, indexed by
+  room name.
+
+### Socket#client:Client
+
+  A reference to the underlying `Client` object.
+
+### Socket#conn:Socket
+
+  A reference to the underlying `Client` transport connection (engine.io
+  `Socket` object). This allows access to the IO transport layer, which
+  still (mostly) abstracts the actual TCP/IP socket.
+
+### Socket#request:Request
+
+  A getter proxy that returns the reference to the `request` that
+  originated the underlying engine.io `Client`. Useful for accessing
+  request headers such as `Cookie` or `User-Agent`.
+
+### Socket#id:String
+
+  A unique identifier for the session, that comes from the
+  underlying `Client`.
+
+### Socket#emit(name:String[, …]):Socket
+
+  Emits an event identified by the string `name` to the client.
+  Any other parameters can be included.
+
+  All datastructures are supported, including `Buffer`. JavaScript
+  functions can't be serialized/deserialized.
+
+  ```js
+  var io = require('socket.io')();
+  io.on('connection', function(client){
+    client.emit('an event', { some: 'data' });
+  });
+  ```
+
+### Socket#join(name:String[, fn:Function]):Socket
+
+  Adds the client to the `room`, and fires optionally a callback `fn`
+  with `err` signature (if any).
+
+  The client is automatically a member of a room identified with its
+  session id (see `Socket#id`).
+
+  The mechanics of joining  rooms are handled by the `Adapter`
+  that has been configured (see `Server#adapter` above), defaulting to
+  [socket.io-adapter](https://github.com/socketio/socket.io-adapter).
+
+### Socket#leave(name:String[, fn:Function]):Socket
+
+  Removes the client from `room`, and fires optionally a callback `fn`
+  with `err` signature (if any).
+
+  **Rooms are left automatically upon disconnection**.
+
+  The mechanics of leaving rooms are handled by the `Adapter`
+  that has been configured (see `Server#adapter` above), defaulting to
+  [socket.io-adapter](https://github.com/socketio/socket.io-adapter).
+
+### Socket#to(room:String):Socket
+
+  Sets a modifier for a subsequent event emission that the event will
+  only be _broadcasted_ to clients that have joined the given `room`.
+
+  To emit to multiple rooms, you can call `to` several times.
+
+  ```js
+  var io = require('socket.io')();
+  io.on('connection', function(client){
+    client.to('others').emit('an event', { some: 'data' });
+  });
+  ```
+
+### Socket#in(room:String):Socket
+
+  Same as `Socket#to`
+
+### Socket#compress(v:Boolean):Socket
+
+  Sets a modifier for a subsequent event emission that the event data will
+  only be _compressed_ if the value is `true`. Defaults to `true` when you don't call the method.
+
+  ```js
+  var io = require('socket.io')();
+  io.on('connection', function(client){
+    client.compress(false).emit('an event', { some: 'data' });
+  });
+  ```
+  
+### Socket#disconnect(close:Boolean):Socket
+    
+  Disconnects this client. If value of close is `true`, closes the underlying connection. 
+  Otherwise, it just disconnects the namespace.
+
+#### Events
+
+- `disconnect`
+    - Fired upon disconnection.
+    - **Arguments**
+      - `String`: the reason of the disconnection (either client or server-side)
+- `error`
+    - Fired when an error occurs.
+    - **Arguments**
+      - `Object`: error data
+- `disconnecting`
+    - Fired when the client is going to be disconnected (but hasn't left its `rooms` yet).
+    - **Arguments**
+      - `String`: the reason of the disconnection (either client or server-side)
+
+These are reserved events (along with `connect`, `newListener` and `removeListener`) which cannot be used as event names.
+
+
+### Client
+
+  The `Client` class represents an incoming transport (engine.io)
+  connection. A `Client` can be associated with many multiplexed `Socket`s
+  that belong to different `Namespace`s.
+
+### Client#conn
+
+  A reference to the underlying `engine.io` `Socket` connection.
+
+### Client#request
+
+  A getter proxy that returns the reference to the `request` that
+  originated the engine.io connection. Useful for accessing
+  request headers such as `Cookie` or `User-Agent`.

-# Angular TodoMVC + Socket.IO
-
-This project was generated with [Angular CLI](https://github.com/angular/angular-cli) version 11.0.4.
-
-Inspired from the [TodoMVC](http://todomvc.com/) [angular example](https://github.com/tastejs/todomvc/tree/master/examples/angular2).
-
-![demo](assets/demo.gif)
-
-## Development server
-
-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-## Socket.IO server
-
-Run `npm run start:server` to start the Socket.IO server.
-
-## Code scaffolding
-
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
-
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
-
-## Running unit tests
-
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
-
-## Running end-to-end tests
-
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
-
-## Further help
-
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.

-Run `ng serve` for a dev server. Navigate to `http://localhost:4200/`. The app will automatically reload if you change any of the source files.
-
-## Code scaffolding
-
-Run `ng generate component component-name` to generate a new component. You can also use `ng generate directive|pipe|service|class|guard|interface|enum|module`.
-
-## Build
-
-Run `ng build` to build the project. The build artifacts will be stored in the `dist/` directory. Use the `--prod` flag for a production build.
-
-## Running unit tests
-
-Run `ng test` to execute the unit tests via [Karma](https://karma-runner.github.io).
-
-## Running end-to-end tests
-
-Run `ng e2e` to execute the end-to-end tests via [Protractor](http://www.protractortest.org/).
-
-## Further help
-
-To get more help on the Angular CLI use `ng help` or go check out the [Angular CLI Overview and Command Reference](https://angular.io/cli) page.
